These are problems that are often
not-well defined. Students have to conduct websearches for relevant information,
or more commonly, make estimates of quantities. This means they must also decide
what information is needed. Many of these problems can be solved in more than
one way, so students have to determine the approach that works best for them.

Some examples of activities from
the classroom and exams:

How many two-step paces is it from
LA to NYC?

What are the dimensions of the
standard kilogram?

How far does a bowling ball get
before it stops skidding and is only rolling?

How many candy bars worth of energy
does it take to push a shopping cart past the snack aisle?
